'anglicification' originates from Modern English, specifically formed from the verb 'anglicify' combined with the Latinate suffix '-fication' (from Medieval Latin/French), where 'Angli' referred to the Angles (a Germanic people) and Latin roots related to 'facere' conveyed 'to make'.

'anglicification' changed from the earlier verb forms 'anglicize'/'anglicise' (Early Modern English) and the back-formation 'anglicify', and eventually the noun 'anglicification' was formed in Modern English by adding the Latinate nominal suffix '-fication'.

Initially it referred broadly to 'making or rendering English' (language, names, customs), and over time it has come to be used specifically for 'the process or result of making something English' in linguistic, cultural, or stylistic contexts.
